Description
Technical Field
The invention relates to the technical field of cultural relic protection, in particular to microwave equipment for reinforcing a surface layer of an earthen site.
Background
Earthen sites are usually ancient building sites, structures and other human activity sites with historic, artistic and scientific values, which are formed by digging, ramming or mixing and building with earthen materials as main bodies. In the key cultural relic protection unit of the whole country, the ancient ruins and ancient tombs mainly comprise 30.2% of the total number, and are distributed in 30 provinces, cities and autonomous areas of the whole country. In addition, there are a large number of earthen sites at the level of "province-insurance" and "city (county) insurance". These earthen sites include large-scale gatherings, urban sites, palace, cemetery and the like ranging from a few square meters of excavation tomb pit to hundreds of thousands of square meters, which relate to politics, religions, military, science and technology, industry, agriculture, construction, transportation, water conservancy and other aspects, have important historical, cultural and scientific values, and can well reflect the social conditions and economic conditions of each historical development stage of China. At present, due to the property of soil body and continuous deterioration of preservation environment, the damage of the earthen site is increasingly serious, and the reinforcement of the protection of the earthen site is already an unprecedented task.
Currently, earthen sites, particularly the surface layers of earthen sites, are susceptible to deterioration due to factors such as natural and human activities. For example, rain water is more likely to cause greater erosion of the surface layer of earthen sites; for another example, the surface layer of the earthen site is more likely to crack after absorbing water. After the surface layer of the earthen site is degraded, irreversible damage is easily generated in the earthen site, and collapse and fragmentation are easily generated. The reinforcement of the surface layer of the earthen site is an important measure for realizing the protection of the earthen site. The method for reinforcing the surface layer of the earthen site is only one chemical reinforcing method at present. The chemical reinforcing method is to apply chemical materials on the surface of the earthen site by brushing, spraying and other methods, and realize the reinforcement of the surface layer of the earthen site through the penetration of the chemical materials, so that the earthen site has certain degradation resistance.
The reinforcement method by adopting chemical material permeation is not suitable for the earthen sites in all areas, so the method has the problems of poor adaptability and low acceptance. Most importantly, chemical materials are more susceptible to aging due to environmental factors, and further, the protective function is more easily lost, so that the problem of shorter effective period exists. After the chemical material is aged, the surface layer of the earthen site is reinforced by adopting a chemical method, so that the problem of difficult retreatment exists. Meanwhile, the cost of chemical materials is high, and for earthen sites with large areas in general, the reinforcing method can definitely lead to high protection cost and high cost pressure for protection. In addition, as the reinforcing materials are generally volatile solvents, the reinforcing materials have great negative influence on the environment and are not beneficial to the environmental protection.

One end of the waveguide 400 is connected to the microwave generator 300, and the other end thereof extends into the protection pipe 500 and extends along the extension direction of the protection pipe 500. The waveguide 400 is disposed in the protection tube 500, and is used for conducting microwaves to the free end of the protection tube 500, and radiating the free end of the protection tube 500 to the earthen site surface layer, so as to heat the earthen site surface layer.
In the working process of the microwave equipment disclosed by the embodiment of the invention, the free end of the protection tube 500 is close to the surface of the earthen site surface layer, the microwave generator 300 is started, and microwaves generated by the microwave generator 300 are thermally radiated towards the earthen site surface layer through the free end of the protection tube 500 under the conduction of the waveguide 400, so that the earthen site surface layer is reinforced through heating.
The microwave generated by the microwave equipment heats the surface layer of the earthen site, so that the surface layer of the earthen site is reinforced, and after the surface layer of the earthen site is heated, partial components in the earth material are subjected to chemical reaction, thereby achieving the purpose of reinforcing.
According to the working process, the microwave equipment disclosed by the embodiment of the invention adopts a physical method of microwave heating to realize the reinforcement treatment of the surface layer of the earthen site, and the surface layer of the earthen site is reinforced block by adjusting the heating position of the microwave equipment in the whole process. Compared with chemical reinforcement, the microwave heating is adopted without considering the adaptability of chemical materials to different environments and soil components, so that the application range of the microwave heating device can be enlarged. The reinforcement is irreversible by adopting microwave heating, so that the problem of failure of chemical protection materials does not exist, and the reinforcement effect can be ensured to play a role for a longer time. Meanwhile, as the pore structure of the soil body is not changed, other reinforcing measures can be conveniently carried out if needed. In the reinforcing process, the microwave equipment is certainly more cost-saving than the application of chemical materials on the surface layer of the earthen site, and the influence of the chemical materials on the environment is avoided.

The auxiliary thermal junction member 520 may be carbon powder, corundum monetite plate, recrystallized silicon carbide plate, ferrite plate, carbon felt or ferrite ring. Preferably, the auxiliary thermal junction member 520 is a ferrite ring.
In this embodiment, the number of microwave generators 300 may be one or at least two. Each of the microwave generators 300 may be connected to the waveguide 400 one by one, that is, each of the microwave generators 300 is connected to the waveguide 400 through one of the waveguides 400.

Of course, the protection tube 500 may be a bent tube, and the other end port of the protection tube 500 may face vertically upward or vertically downward, so as to heat the surface layer of the earthen site in the horizontal direction.
In the preferred scheme, the protection pipe 500 can be formed by splicing a plurality of pipe sections, and each pipe section splices the protection pipe 500 with different bending angles through the bending direction of the pipe section, and in this case, an operator can splice according to the actual condition of the earthen site surface layer to form the protection pipe 500 that suits. Of course, as described above, the waveguide 400 is disposed inside the protection tube 500 to extend along the extension direction of the protection tube 500. Accordingly, the waveguide 400 may be a structure formed by splicing a plurality of pipe sections.
